- Enhanced linting rules in `src/proxy/mod.rs` to enforce stricter code quality checks in production.
- Updated hash functions in `src/proxy/middle_relay.rs` for better efficiency.
- Added new security tests in `src/proxy/tests/middle_relay_stub_completion_security_tests.rs` to validate desynchronization behavior.
- Removed ignored test stubs in `src/proxy/tests/middle_relay_security_tests.rs` to clean up the test suite.
- Improved error handling and code readability in various transport modules, including `src/transport/middle_proxy/config_updater.rs` and `src/transport/middle_proxy/pool.rs`.
- Introduced new padding functions in `src/stream/frame_stream_padding_security_tests.rs` to ensure consistent behavior across different implementations.
- Adjusted TLS stream validation in `src/stream/tls_stream.rs` for better boundary checking.
- General code cleanup and dead code elimination across multiple files to enhance maintainability.
- Introduced regression tests for relay quota wake liveness to ensure proper handling of contention and wake events.
- Added adversarial tests to validate the behavior of the quota system under stress and contention scenarios.
- Implemented security tests for the TLS stream to verify the preservation of pending plaintext during state transitions.
- Enhanced the pool writer tests to ensure proper quarantine behavior and validate the removal of writers from the registry.
- Included fuzz testing to assess the robustness of the quota and TLS handling mechanisms against unexpected inputs and states.
- Rename MAX_TLS_RECORD_SIZE to MAX_TLS_PLAINTEXT_SIZE for clarity.
- Rename MAX_TLS_CHUNK_SIZE to MAX_TLS_CIPHERTEXT_SIZE to reflect its purpose.
- Deprecate old constants in favor of new ones.
- Update various parts of the codebase to use the new constants, including validation checks and tests.
- Add new tests to ensure compliance with RFC 8446 regarding TLS record sizes.
This commit introduces the `into_inner_with_pending_plaintext` method to the `FakeTlsReader` struct. This method allows users to extract the underlying reader along with any pending plaintext data that may have been buffered during the TLS reading process. The method handles the state transition and ensures that any buffered data is returned as a vector, facilitating easier management of plaintext data in TLS streams.
- Implemented a mechanism to log unknown datacenter indices with a distinct limit to avoid excessive logging.
- Introduced tests to ensure that logging is deduplicated per datacenter index and respects the distinct limit.
- Updated the fallback logic for datacenter resolution to prevent panics when only a single datacenter is available.
feat(proxy): add authentication probe throttling
- Added a pre-authentication probe throttling mechanism to limit the rate of invalid TLS and MTProto handshake attempts.
- Introduced a backoff strategy for repeated failures and ensured that successful handshakes reset the failure count.
- Implemented tests to validate the behavior of the authentication probe under various conditions.
fix(proxy): ensure proper flushing of masked writes
- Added a flush operation after writing initial data to the mask writer to ensure data integrity.
refactor(proxy): optimize desynchronization deduplication
- Replaced the Mutex-based deduplication structure with a DashMap for improved concurrency and performance.
- Implemented a bounded cache for deduplication to limit memory usage and prevent stale entries from persisting.
test(proxy): enhance security tests for middle relay and handshake
- Added comprehensive tests for the middle relay and handshake processes, including scenarios for deduplication and authentication probe behavior.
- Ensured that the tests cover edge cases and validate the expected behavior of the system under load.
- Remove unused imports across multiple modules
- Add #![allow(dead_code)] for public API items preserved for future use
- Add #![allow(deprecated)] for rand::Rng::gen_range usage
- Add #![allow(unused_assignments)] in main.rs
- Add #![allow(unreachable_code)] in network/stun.rs
- Prefix unused variables with underscore (_ip_tracker, _prefer_ipv6)
- Fix unused_must_use warning in tls_front/cache.rs
This ensures clean compilation without warnings while preserving
public API items that may be used in the future.
